Calculate the mass of dissolved nitrogen at 25°C in an aquarium containing 77.2 L of water. Assume the total pressure is 101.8 kPa and the mole fraction of nitrogen in air is 0.78. It is recalled that the partial pressure of a gas in a gas mixture can be determined from the total pressure and its mole fraction (Dalton's Law). Give an answer with 2 decimal places.
